The Shali fortress which is located far away in Egypt's Western Desert, once was protected inhabitants against the incursions of wandering tribes. However, now it has became a source for ecotourists.
"Shali" means "home" in the local Siwi language, the fortess was created by Berber populations atop a hill in the pristine Siwa oasis, southwest of Cairo.
Moreover, the towering structure is made of kershef -- a mixture of clay, salt and rock which acts as a natural insulator in an area where the summer heat can be scorching.
